Assembly is consuming and costliness.
In addition a kind of known door hinge being made of a small amount of component and its manufacturing method from 102009031829 A1 of DE.
The door hinge is characterized in that the bearing section of external door hinge chain part is by rotation or cold extrusion manufacture and outside it
It is closed on the end side in portion.On the end side of the bearing section of its door hinge chain part inside, or external door hinge portion
There is the bearing section of part protrusion, the protrusion to be joined in sliding section, the door hinge portion inside the sliding section loading
In the bearing section of part;Either the bearing section has the sliding members or bolt shape of the door hinge chain part inside recess portion
Component in the recess portion.As shown in Fig. 3 in 102009031829 A1 of DE, external door hinge chain part
The bottom for supporting the blind hole of the formation recess portion of section, has a complicated hemispherical shape, the shape be during manufacturing it is complicated and
Expensive.
Invention content
The object of the present invention is to improve the known door hinge from 102009031829 A1 of DE so that do not need complexity
Ground manufactures the hemispheric bottom of blind hole.
The purpose is realized according to the present invention by the door hinge of the feature with claim 1.Door according to claim 1
Other advantageous design schemes of hinge are generated by quoting the feature of the dependent claims of claim 1.
Door hinge according to the present invention is characterized in that the door hinge is by waiting for that the component simply manufactured forms.Therefore, outside
The bearing section of the door hinge in portion easily can manufacture or be fabricated to turning part by solid profile, have bottom as flat as possible
The blind hole drilling of the end side of wall is machined into the bearing section.The two sliding sleeve elements being especially advantageously made of plastics
With it is being disposed there between, can be beneficially based on sphere made of metal be set to the blind hole drilling in, wherein the first sliding sleeve
Element sticks on the bottom wall of the blind hole of bearing section.
Sliding sleeve element has the bearing surface of the spherical segment for sphere so that is only generated by big slide area small
Frictional force is to correspondingly generate small abrasion.
The bearing section of internal door hinge chain part forms protrusion by two axial end portion, and the protrusion engages respectively
To in the recess portion of the end side of the second sliding sleeve element and being supported on its bottom wall as flat as possible.The element rotational symmetry
Ground is constituted so that the element can be rotated one another around its axis.
Obviously also it is possible that the bearing section of external door hinge chain part have with before the door hinge chain part of inside
The corresponding protrusion of described bearing section, wherein the bearing section of internal door hinge chain part therefore must have it is corresponding,
In the blind hole drilling that end side introduces, sliding sleeve element and sphere are fitted into the blind hole drilling.
Equally, for the present invention, the bearing section of internal door hinge chain part has convex on the end of an axial direction
Portion and there is blind hole drilling on another axial end side, wherein therefore the bearing section of external door hinge chain part must have
There is corresponding blind hole drilling and another bearing section there must be corresponding protrusion.
After all parts for assembling door hinge according to the present invention, bearing section is connect with flap, this can
It is realized by weld seam.When welding together, the bearing section of external door hinge chain part mutually must squeeze or shift onto one
It rises and is maintained as so that manufactured door hinge is gapless.
Sphere and sliding sleeve element are advantageously made from a variety of materials, and the material has good sliding capability jointly.
